Old table values are persisting under the new values

[DavidPL]

I am displaying data on a table. The old values are not being erased. As a result, the digits become unreadable blobs. I have seen this before on a different computer, using a different version of LabVIEW. Any suggestions?

Thanks

I've never seen that. Can you post a screenshot? What is your LabVIEW version? What is the OS (windows, mac, linux, etc.)? Does it clear up if you e.g. move the window?

It might just be a problem with you graphics adapter. Is there a newer driver available? In windows, you could try the troubleshooting option in the control pane and turn it down a few notches.

LabVIEW version is 8.20. I've tried the video trouble shooting options with no results. Scrolling the window gives a very temporary relief, as the update rate is pretty fast. I'll check for video driver updates.

Hey David,
      This is definitely a head-scratcher.  Could you post a VI that shows this behavior, or even a screenshot of it occurring?  What methods are you using to write to the table?

I can not send a snapshot, as we were having the Click on the table and have LabView crash issue as well. So I placed a transparent decoration over part of the table, recompiled, and both problems went away. I also changed the table to "Smooth Scrolling".
